MSI Detective Services helps businesses investigate sensitive concerns and gather facts for informed decisions. Serving clients since 1959, we provide discreet business investigations in Chicago for owners, managers and their attorneys.
Whether you are examining unexplained losses, suspected misconduct or a security concern, we begin by defining the questions to answer, reviewing available information and agreeing on a practical investigative scope.
Business Matters We Investigate
- Employee theft and unexplained losses, including inventory and property concerns.
- Fraud and embezzlement concerns requiring fact finding and documentation.
- Vandalism, sabotage and other workplace security matters.
- Employee contract and competition related fact finding in coordination with your attorney.
- Trademark, patent and copyright investigations.
- Business intelligence and due diligence questions.
- Privacy concerns addressed through bug sweeps and electronic countermeasures.
An Approach Suited to Your Business
Depending on the assignment, investigative methods may include surveillance, interviews, witness statements, background research or undercover investigations. We discuss the proposed methods and how the work can be organized around your operations.
Relevant records, a timeline of events and a clear description of the concern help us assess the next steps. Tell us who is authorized to coordinate the investigation and whether legal counsel is involved.
Documentation You Can Review
Our work focuses on documenting findings and separating observed facts from assumptions. We discuss reporting needs at the outset so the results can support your internal review or your attorney’s assessment.
The scope, schedule and cost depend on the questions involved and the information available. A consultation can help determine which services are appropriate for your business.
